  • 460 BCE

    Democritus

    He lived in 400 B.C.E., and introduced the atom. Leucippus had the biggest influence on him but he is credited with the idea of the atom.
  • 322 BCE

    Aristotle

    Aristotle lived from 384 to 322 B.C.E. and is known for his work on the elements. Aristotle created what he thought were the only elements earth, water, fire, and air.
  • Antoine Lavoisie

    Antoine Lavoisie lived from 1743 to 1794 and is best known for writing the first extensive list for elements and oxygen's relation to combustion.
  • John Dalton

    John Dalton lived from 1766 to 1844, and he is best known for his work on atomic theory and his work into color blindness. John Dalton also proposed the Billiard Ball model that said that all matter was composed of atoms and that atoms were the smallest particles of matter.
  • Quantum Model

    The Quantum Model was created in 1926. The model uses mathematical equations to find where an electron will be at a certain time. This model is based of of probability rather than certainty.
  • Marie Curie

    Marie Curie lived from 1867 to 1934. She is best known for her pioneering research on radioactivity. She was the first woman to win a Nobel Prize and the only woman to win one in two different sciences.
  • Ernest Rutherford

    Ernest Rutherford lived from 1871 to 1937 and is well known as the "Father" of nuclear physics. Ernest attended Victoria University of Manchester. Rutherford also proposed the nuclear model that stated all atoms have a small dense nucleus.
  • JJ Tomson

    JJ Tomson lived from 1856 to 1940, he is best known for his discovery of the electron and his atomic structure models. JJ Tomson attended Cambridge University and Trinity. JJ Tomson is also credited with creating the Plum Pudding model that states that atoms are composite objects made of positive and negative charge.
  • Max Planck

    Max Planck lived from 1858 to 1947 and is best known for his contributions on the atomic and subatomic process. Max was a professor at a college in Germany for 39 years.
  • Neils Bohr

    Neils Bohr lived from 1885 to 1962 and is best known for his contributions on quantum theory and atomic structure. Neils won the Nobel Prize in 1922 and was also a philosopher. Bohr is credited with the creation of the Bohr model which states that negatively charged electrons orbit a positively charged nucleus.
  • Louis de Broglie

    Louis de Broglie lived from 1892 to 1987 and is known for his contributions toward quantum physics. Louis won the Nobel Prize for physics in 1924 after his demonstration on how matter acts in waves.
